Frequently Asked Questions
Why compress to 500KB instead of the smallest size?
A 500KB target keeps scanned pages and photos clearer than 100KB or 200KB while still fitting most online forms and email limits.
Will the text still be readable?
Yes. MyPDF recompresses the images inside the PDF and keeps text as text, so it stays sharp and selectable. Pages are only turned into images if that is the only way to reach the size.
What if the file is still over 500KB?
Try the High compression level, convert the PDF to grayscale, or remove pages you do not need, then compress again. Very long scans may need to be split.
Is my document uploaded anywhere?
No. Compression runs entirely in your browser, so certificates, IC copies and payslips never leave your device.
